This study investigated the effect of dietary resveratrol supplementation on growth performance, rectal temperature, and serum parameters of yellow-feather broilers under heat stress. A total of 480 yellow-feather broilers (28-day-old) were randomly allotted to five groups with six replicates. A thermoneutral group (TN) (24 ± 2°C) received a basal diet and another four heat-stressed groups (37 ± 2°C for 8 hr/day and 24 ± 2°C for the remaining time) were fed the basal diet or basal diet with 200, 350, and 500 mg/kg resveratrol for 14 conse...
